-LRB- CNN -RRB- -- Five more Georgia men were charged in connection with an anti-government militia with ties to Fort Stewart that 's been accused of killing two people and plotting to assassinate President Barack Obama , authorities said Tuesday .

The five defendants were indicted in Liberty County , Georgia , on charges that include violation of the Street Gang Terrorism and Prevention Act , involving what prosecutors called an `` identified criminal street gang '' named FEAR , for Forever Enduring , Always Ready .

Four U.S. Army soldiers at Fort Stewart had already been accused of being members of the anarchist group , which was allegedly stockpiling weapons and bomb parts to overthrow the U.S. government , prosecutors said .

The four soldiers are accused of killing former GI Michael Roark and his teenage girlfriend , Tiffany York .

` Anarchists ' accused of murder ; broader plot against government

Under one of three indictments returned Monday by a Liberty County grand jury , Christopher Jenderseck was charged with three Street Gang Act violations and two counts of tampering with evidence in the killings of Roark and York in neighboring Long County , said District Attorney Tom Durden and Assistant District Attorney Isabel Pauley of the Atlantic Judicial Circuit .

In a second indictment , defendant Timothy Martin Joiner is charged with burglary , theft by taking and two Street Gang Act violations . Adam Dearman is charged with three Street Gang Act offenses .

In the third indictment , Joiner , Adam Dearman , Randall Blake Dearman and Anthony Garner are charged jointly , prosecutors said . Joiner and Randall Dearman each face two counts of burglary , nine counts of entering an auto , two counts of financial transaction card theft , one count of theft by taking , one count of criminal damage to property in the second degree , and 14 counts of Street Gang Act violations , prosecutors said .

In addition , Adam Dearman is indicted on three counts of Street Gang Act violations , and Garner is charged with theft by receiving stolen property and one Street Gang Act count , prosecutors said .

Jenderseck was arrested Tuesday in North Dakota , but Joiner and Garner were n't in custody , authorities said Tuesday .

Regarding the charges against the four soldiers , a law enforcement official said they had legally purchased at least 18 rifles and handguns in Washington and Georgia .

Uncompleted pipe bombs were also found , and were comprised of store-bought materials , the official said . No sophisticated military grade-explosives were involved in their construction .

One official described the offenses as a murder case and said no federal charges had been filed .

Last month , Pfc. Michael Burnett laid out the elaborate plot , telling a southeast Georgia court that he was part of what prosecutors called `` an anarchist group and militia . ''

Dressed in his Army uniform , he spoke in a Long County court about the group of Army soldiers and its role in the December deaths of Roark and York .

Roark , he said , was killed because he took money from the group and planned to leave .

`` I do n't know how it got to the point where two people got murdered , '' Burnett said in court .

He talked about how he and three others accused -- Pvt. Isaac Aguigui , Sgt. Anthony Peden and Pvt. Christopher Salmon -- had begun getting together , `` just going out shooting guns , just guy stuff . ''

`` And then Aguigui introduced me to ` the manuscript , ' that 's what he called it , a book about true patriots , '' the soldier said .

The four men became part of a group that aimed `` to give the government back to the people , '' according to Burnett , who said that revolution was its goal . They called it FEAR -- Forever Enduring Always Ready -- and spent thousands of dollars buying guns and bomb parts .

The government needed a change , Burnett told the court . `` I thought we were the people who would be able to change it . ''

It is not clear how capable the group was of carrying out the goals Burnett laid out .

Assistant District Attorney Pauley identified Aguigui as the leader of what she described as `` an anarchist group and militia '' that included active and former troops .

`` Defendant Aguigui actively recruited new members at Fort Stewart -LRB- in southeast Georgia -RRB- and targeted soldiers who were in trouble or disillusioned , '' she said .

At the time of their arrest , group members had plotted a number of `` acts of domestic terror , '' the prosecutor said .

These included `` forcibly taking over the ammo control point of Fort Stewart to take the post , bombing vehicles of local and state judicial and political figureheads and federal representatives to include the local department of homeland security , -LRB- and plotting -RRB- to bomb the fountain at Forsyth Park in Savannah . ''

Days before he died , Roark had been discharged from the Army , according to Pauley .

Roark and his girlfriend were killed because Aguigui felt the couple was `` a loose end , '' Burnett said .

Burnett admitted being at the scene of the crime , including watching as a soldier `` checked -LRB- York 's -RRB- pulse and then shot her again . ''

As part of an agreement with prosecutors , Burnett pleaded guilty to manslaughter -- instead of murder , thus avoiding a possible death sentence -- and other charges . He also agreed to testify against the three other soldiers accused in the case .

All four soldiers had also been charged by the military in connection with the two killings . But as their case proceeded through civilian courts , the Army dismissed its charges , according to Fort Stewart spokesman Kevin Larson .

In a statement last month , Larson insisted that Fort Stewart and its affiliated Hunter Army Airfield do not have `` a gang or militia problem . ''

`` Any suspicions of gang activity are actively investigated by CID , -LRB- which -RRB- recognizes the obvious concerns with the combination of gangs and military-type training , '' he said .

`` That is why CID monitors and investigates gang and extremist group association with criminal acts in the Army so closely . We believe the reason we are able to maintain a low gang criminal threat status is because of the awareness of and focus on the threat . ''

Fort Stewart , about 40 miles southwest of Savannah , is home to the U.S. Army 's 3rd Infantry Division .

Tens of thousands of troops , their dependents , civilian personnel and contractors live and work on the base , which encompasses 280,000 acres and includes parts of five counties , including Long County , which has about 14,500 residents . Hunter Army Airfield is in Savannah but is officially part of the larger Fort Stewart complex .

The Southern Poverty Law Center , which tracks what it characterizes as `` hate groups '' nationwide , spoke to Aguigui 's father last month .

`` I served my country for 20 years and I honor that , take pride in that , '' Ed Aguigui told the center , according to the center 's Hatewatch blog . `` I do n't know what my son 's views are , and where they came from . ''
